Plan to be early. Setting up always takes longer than the shoot itself. While you’re setting up, the music artist may rehearse or get in makeup/hair and costume. Play the song on the stereo while doing several dry runs to test the lights, composition, and camera movement, if any.
When shooting footage, capture various angles and shots. Composing asymmetrical shots are more dynamic than symmetrical ones. Capture the energy of the musicians and performers. Have the song play over and over and have the music artist run through it as many times as you see fit. If you need to stop the song to capture the first verse again, have someone ready to assist you with the audio system so you won’t be having to go back and forth.
Shoot cutaways of action, such as fingers strumming guitar strings, drum sticks on the cymbals. Where’s the most action taking place? Shoot it. The more footage you have, the better - even if it’s not preconceived or written in the script. Besides, you most likely will receive more ideas once on set, and working with extra footage serves as a great cushion.
If choreographed dancing is in the video, be sure to capture the dance from different angles and shots.
Take regular breaks. During breaks go over shooting script and call sheet and make further plans if needed. You may also want to capture a live performance at a public venue. Unfortunately, it’s a one-take shoot; however, if you make a mistake some of the footage still may serve as great cutaway shots, particularly a crowd’s positive reaction to the music. If you have another camera, use it - perhaps to capture a wider shot.
